Patent DE-19600489-A1 (DE)
Title: Condensation laundry dryer has heat exchanger
Inventor: JORDING WOLFHARD
IPC: D06F58/20
Filed: 1996-01-09
Abstract: The condensation dryer  has a heat pump and an air circulation system. The process air current is led via the liquefier of the heat pump in order to be heated and subsequently guided into an air inlet of a drying chamber containing the washing. For cooling, the process air is led, at least in part, from an air outlet of the drying chamber via a heat exchanger containing the evaporator of the heat pump. The heat exchanger surfaces of the heat exchanger are designed in such a way that a self-cleaning of the heat exchanger surfaces takes places with a simultaneous filtering of the process air current.

Title: Flow-restrictor for hardening liquid forming water-barrier in absorbent body against rising damp
Inventor: TERBORG HERMANN
IPC: E04B1/64
Filed: 1996-01-19
Abstract: The pipes (1) deliver the liquid from a storage vessel to drillings in the solid absorbent body, so as to form a capillary water-barrier in the latter. The main body (2) accommodates a clamping one (3) moved by an actuating member (4) in it.  The pipes pass through drillings (5) in the main body (2), and from which they emerge in an area between parallel faces on the two bodies. Movement of the clamping body squeezes them so as to give a reduction, which can be reversed, of their free cross-sectional area. Mating internal and external cone faces can be formed in and on the bodies, the intervening gap (9) between them being adjustable by movement of the clamping body.

Title: Exhaust gas feedback selection method for multi-cylinder IC engines
Inventor: HUNKERT STEFFEN DIPL ING
IPC: F02B3/06
Filed: 1996-05-23
Abstract: The method includes the step of operating a combustion engine with exhaust fume redirection, determining a residual oxygen proportion individually for each cylinder, and storing the resulting values. The residual oxygen proportion is used as a measure for the exhaust fume quantity led back to the cylinders. Different measurements are taken by changing the sampling point (16) of redirected exhaust fume quantity in the exhaust fume system (1), and/or by changing the injection point (15) of the redirected exhaust fume quantity in the inlet system (2), and/or by changing the geometry of the inlet system (2). The stored values are compared in a comparator of an electronic evaluation system, and new settings are undertaken, if the measurements indicate a worse distribution of the redirected exhaust fumes on the cylinders.

Patent DE-19654710-A1 (DE)
Inventor: WIMMER MARTIN
IPC: F02B25/04
Filed: 1996-12-30
Abstract: In a process for generating a physical power with reciprocating internal combustion engines, in at least one piston-cylinder unit a piston reciprocates within a cylinder and the reciprocating movement is transmitted by a connecting rod to a crankshaft. The piston compresses a mixture of fresh gas and fuel, which is then ignited and moves the piston in the opposite direction. The resulting exhaust fume pressure wave flows into an appropriate exhaust system (resonance exhaust system) designed with a diffuser, cone, matching cone and end tubular nozzle in which negative pressure and counter-pressure waves are generated. The thus generated negative pressure wave empties the cylinder chamber and aspirates fresh gas through an inlet, whereas the counter-pressure wave generated in the exhaust system loads additional fresh gas. These negative and counter-pressure waves cause a gaseous exchange in the area of the bottom dead centre, without requiring that the piston reciprocates through an empty stroke as in the four-stroke process or that the crankshaft chamber below the piston be crossed by a flow of gas as in the two-stroke process. Four embodiments of the reciprocating internal combustion engine are thus possible, in which the exhaust gas pressure wave resulting from combustion flows out of the cylinder chamber into an appropriate exhaust system (resonance exhaust system) through at least one outlet channel, either directly through the cylinder wall or through a valve opening arranged in the cylinder head and closable by at least one outlet valve. Fresh gas is aspirated into the exhaust system by the negative pressure wave generated therein and flows through an inlet channel into the cylinder chamber, either directly through the cylinder wall or through a valve opening arranged in the cylinder head and closable by at least one inlet valve. The overpressure wave generated in the same exhaust system causes the cylinder chamber to be charged with gas.

Title: Boiling water reactor filling level measurement
Inventor: HAMPEL RAINER PROF DR ING
IPC: G01F23/288
Filed: 1997-09-19
Abstract: The filling level in a BWR is measured by using internal  psi radiation sources and a measuring lance between the pressure vessel wall and the biological shield, an n-dimensional characteristic field being formed from a normalized shape function of the sensor signals and from process signals. Autonomous monitoring of the system is effected by comparing the verified characteristic field with hydrostatic operating instrumentation measurements. The filling level in a BWR is measured using internal  psi  radiation sources by: (a) acquiring level information from the complex  psi radiation field surrounding the reactor by means of sensors arranged along a measuring lance positioned vertically between the pressure vessel wall and the biological shield; (b) delivering the information to an n-dimensional characteristic field formed by a neural fuzzy logic method from a normalized shape function of the sensor signals and the neutron flux, pump rotation rate and control rod position process signals; (c) calibrating the measuring system using hydrostatic level measurement signals for normal and abnormal operation; (d) detecting level shifting from the active measuring region of the lance; and (e) carrying out autonomous monitoring of the measuring system by comparing the results of the verified characteristic field with the measurements of the hydrostatic operating instrumentation.
